RSS stands for Real Simple Syndicate. Syndication basically means distributing something (usually copyrighted work) to a large number of services which then publish, show, etc that work for you. When it comes to TV shows, newspaper articles, and pictures, it usually means money. RSS is just a type of electronic way to syndicate or feed your newest post to the world.
In the Blogosphere, Syndication means you get to syndicate your article for free to anyone who will listen. An RSS feed is what bloggers and internet news sites use to alert people that there is new content on their websites. Readers, like you, and I, have programs called feedreaders that are usually based online and can be accessed from any computer. When you log in all the blogs or newspapers feeds that you are subscribed to are downloaded, most of these are RSS but there is also Atom feeds and XML feeds that do pretty much the same thing.
If you look on the far right bar of this blog you’ll see some buttons labeled RSS, XML, add to google, etc. If you click on those buttons you can add this blogs feed to stay up to date with all the newest information for part time bloggers. If you don’t have a feed reader don’t worry just clikc on the button and you’ll be able to sign up for a feed reader without losing this blogs info.
